1.2083 is a martensitic stainlesstool steel with high chromium content (-13%), giving it excellent corrosion resistance,high wear resistance,and good polishability,It is typically supplied in the quenched and tempered condition with hardness ranging from 48-52 HRc. Its ability tomaintain a high surface finish and resist attack from chemically aggressive plastics makes it a premium choice for demanding mold applications.

Heat the steel evenly to 820–840°C until the whole section reaches temperature. Then quench in oil to cool.
Heat the steel uniformly to about 900°C to achieve a normalized structure.
Heat P20 steel to 770–790°C, hold it well at temperature, and then let it cool slowly inside the furnace.
Heat the steel evenly and hold it for at least 1 hour per 25 mm of thickness at the chosen tempering temperature. Allow it to cool in still air.
